How does human sperm move?
- A. Flagella
- B. Cilia
- C. Neutrophils
- D. None of the above
Correct Answer: A
Rationale: Human sperm moves using flagella, which are whip-like structures that aid in propulsion. Flagella are tail-like structures found in sperm cells and help them swim towards the egg for fertilization. Cilia are shorter, hair-like structures that are not involved in the movement of sperm. Neutrophils are a type of white blood cell involved in the immune response and are not related to sperm locomotion.
Which of the following is a contraceptive?
- A. Copper T
- B. Condom
- C. Diaphragm
- D. All of these
Correct Answer: D
Rationale: The correct answer is D, All of these. Copper T, Condom, and Diaphragm are all examples of contraceptives used to prevent pregnancy.
